June 28, 20206 yr Hey, So i started a new array for the first time and i started it in Maintenance mode initally and not the normal mode, i have no idea why. It showed the Parity drive as invalid and green check on the data drive. I searched online and i read that it is because it is currently doing a preclear? so i am waiting, its a 14tb wd elements white label drive. Its been a day (24hrs + 40minutes) and in still shows up like that. Was it just idling the whole time? do i have to start the array in normal mode and not maintenance mode for it to actually preclear? or should i wait longer for it...? i thought it was doing somethign because its temp was higher than the other drive thats why i waited but it seems like thats not it? is there a way to check if preclear is actually being performed right now or is some sort of percentage value i can find?
June 28, 20206 yr Community Expert Are you sure you are trying to do a pre-clear? This should not be allowed on a drive that has been assigned to the array regardless of the mode that it is running in.
June 28, 20206 yr Community Expert Starting the array in maintenance mode won't auto-start the initial parity sync, you need to press the "Sync" button next to array start/stop buttons, or better yet, stop the array and re-start it in normal mode, parity sync will auto-start.
